Brand new czechmate issues

Recommended Posts


Look, it's a new gun.  It will take 500 rounds before everything smooths out all by itself.  Stop sanding and polishing.  Load your mags fully and let them sit for at least a full week.  If you shoot sooner, fill them again and let them sit.  After two weeks the springs will have taken a set and feeding will be smooth.


You opened you feed lips too wide and that caused your later problem.  Close the front up slightly so the top round points to the top of the feed ramp, not the chamber.  You should not have to ream the chamber.  If you want to load long because you are using  a fluffy powder, you may have to throat your barrel, not ream the chamber.


Here is a picture showing case fills for Major with a 115gr bullet.
